REM were pretty much the masters of the album closer at one point, as Find The River, Wendell Gee and Electrolite, among others, prove. Unfortunately the album closer on their last album was one of the worst songs I've ever heard from a credible band.

...saving the best for last...

Back And Forth (Dismemberment Plan, Emergency & I) - where Travis Morrison blows most of the world's MCs out of the water with some absolutely stunning verses which pretty much detail our existence in a more beautiful and true way than you could ever imagine. And the last line is killer: "You'll always be my hero, even if I never see you again."

and the last track off Spiritualized 'Ladies and gentlemen...' whose name escapes me now - epic stuff

Redundant because someone alresdy said above by I vote for Find the River off Automatic for the People... and would add that it being preceded by Nightswimming make them the two best tracks to close an album...

last track on the new rilo kiley record, last track on remote part (idlewild), last track off music has the right to children (Boards of Canada), hitting women, off of Cold Water Songs (Broken Family Band)

millions more im sure, but im too annoyed to type - have just broken my power cable on my laptop AND lost my bankcards.

patrick wolf-a boy like me off lycanthropy(sort of the closing track, epilogue isnt really a track)
Pulp-bar italia off different class
idlewild-you just have to be who you are off captain
stone roses-i am the resurrection of the stone roses
REM-electrolite off new adventures in hifi
